The invention relates to a concrete pump, comprising: —a frame; —a supporting leg, the supporting leg having a supporting foot, the supporting foot being extensible relative to the supporting leg; and—a drive for driving a movement of the supporting leg relative to the frame. A camera image of a hazard zone around the supporting leg is produced by a monitoring sensor. The drive is controlled by means of a remote control. The data information is transferred to the remote control via an interface. The invention also relates to a method for supporting a concrete pump. On the basis of the received data information, it can be determined, by means of the remote control, whether the movement of the supporting leg causes a hazard.

Described is a self-propelled operating machine (1) equipped with stabilizers which comprise a front stabilizing unit (2), mounted on a chassis (100) of the machine (1), which is movable on wheels and is fitted with a driver's cab (12) for an operator (O). The stabilizing unit (2) comprises a supporting frame (24) and two stabilizing arms (21, 22, 23), each of which includes a first segment (21) hinged to the frame (24) by a pin (25) located at a lower side of the first segment (21).

The independent hydraulic jack system uses four independent jacks strategically mounted on the four corners of the bottom of a vehicle. Each of the jacks is connected via hydraulic hoses to a central hydraulic pump, also mountable on the bottom of the vehicle. The hydraulic pump can raise or lower any of the four jacks without affecting the other three. This hydraulic pump is controlled by a user-operated remote control whereby the user can directly adjust the height of the four jacks. The control also has a locking feature whereby the jacks will not alter their height until the control is unlocked. As a safety precaution, the pump cannot be utilized unless the vehicle brakes are applied.

A support foot (100) comprising: a first body (105), a second body (110) slidingly coupled to the first body (105) along a predetermined sliding direction (A), an actuator device (150) adapted to actuate the second body (110) to slide with respect to the first body (105) along said sliding direction (A) between a retracted position and an advanced position, a third body (115) hinged to the first body (105) according to a hinging axis (B) orthogonal to the sliding direction (A) of the second body (110), and an actuation apparatus adapted to actuate the first body (105) to rotate with respect to the third body (115) around said hinging axis (B) between an active configuration and an inactive configuration, wherein said actuation apparatus comprises a mechanism adapted to transform a sliding of the second body (110) from the advanced position towards the retracted position into a corresponding rotation of the first body (105) from the active configuration to the inactive configuration.

A stabilizer leg arrangement with a stabilizer leg (25), which is extensible by a hydraulic cylinder (27) into a supporting position in contact with the ground. A piston (32) divides the internal space of the hydraulic cylinder into first and second chambers (34, 35), wherein these chambers are configured to come into fluid communication with each other through a flow channel (41) in the hydraulic cylinder when the piston reaches an advanced end position and abuts against a stop surface. An electronic control device (72) is configured to establish information as to whether or not the stabilizer leg is in the supporting position while taking into account a measuring value (V1) related to the hydraulic pressure in the first chamber (34). The invention also relates to a corresponding method and a mobile working machine comprising such a stabilizer leg arrangement.
